IMPROVEMENT IN SEAL-LOCKS..

Specification forming part of Letters Patent No. 165,915, dated July 27,1875; application filed February 24, 1875.

To all whom it may concern: I

Be it known that 1, JOHN S. BROWN, of Indianapolis, Marion county, Stateof Indiana, have invented an Improvement in Oar-Locks and Seals, ofwhich the following is a specification:

The object of my invention is to construct a lock with proper tumblers,with a key to operate them. The locking device and key-hole are tobe-covered up with a hinged cover, and a seal is to be inserted in thefront of the cover, so that when the cover is let down over the key-holethe seal shall project downward and over the bolt hole. in front of thebody of the lock. The bolt is provided with a notch on one side, andpasses through guides, and the holein the projecting part of the seal,into the front of the lock, forcing the tumblers back until the notchinthe end of the bolt has passed them, Whenthey close up in the notch andhold it securely fastened, so that it cannot be opened until the seal isbroken, so as to allow the cover to be raised and the key inserted, andpress the tumblers back, when the notched bolt can be removed and thecar is unlocked.

Figure 1 represents my improved lock and seal in its position on a car.Fig. 2 is a top view of my improved lock and seal. Fig. 3 is a sideelevation of the same. Fig. at is a side elevation of the same, with thecover turned up, and the seal inserted in the front O represents thekeyhole coverof of the lock are arranged tumblers, of any number, formedwith hooks on the ends, so as to engage with the notch in the end of thebolt H. These tumblers are operated by a key, T, which is inserted inthe top of the lock and under the cover 0, as shown in Fig. 4. Erepresents the seal, made of iron, or any other material, so that it isbrittle, and has a form of a right angle. The part marked 0, Fig. 6, isinserted into the hole M of the cover 0,

Fig. 5, and the notches O O slide over the projections N N wheninserted, and the cover 0 is then ready to close down, as in Fig. 3,after the key has been removed. When closed down, as in Figs. 2 and 3,that part of the seal marked G projects downward in front of the lock,until the hole P comes opposite the bolt-hole in the front of the lock;then the hasp or bar Kis placed between the lugs JJ, and bolt H isinserted into the holes in the lugs J J, over the bar K, and the notchedend is forced through the hole P in the seal into the lock, thus closingup all comm unication with the key-hole of the lock until the JOHN S.BROWN.
